Attempts have been made to clarify polarization behavior of aluminum alloy 1050 in 30 mass%nitric acid solution which is in deaerated and stagnant solution condition. It is shown that the dissolution of aluminum behaves in the fast and like a general dissolution manner when the 1050 specimen was dipped into the solution. It was found that the corrosion rate of 0.25 mA·cm−2 obtained from the corrosion weight loss roughly corresponded to the current density of 0.29 mA·cm−2 on the assumption that the dissolution of aluminum in the nitric solution is categorized to electrochemical reaction of the fast system.
